Polling day is approaching in the same-sex marriage referendum - with opinion polls showing a big support for a Yes vote.

A Red C poll last month found that while a large majority of 77% support same-sex marriage, almost half of voters - 46% - have "some reservations" over the issue.

It is thought that urban areas - such as Dublin - could see a big swing towards a Yes vote. But what about rural communities?

Newstalk's reporter Andrea Gilligan went to the north-west, and got the views of local farmers at a mart in county Sligo. While many were reticent to speak on the upcoming referendum at all, some did express their concern about the effect same-sex marriage could have on parenting.

“The biggest problem is children...It may be alright for two women but two men? Out of order,” one farmer said.

While others admitted they would not be compelled to go to the polls in May, stating: "I wish them the best of luck but I wouldn’t be voting for it."

However, another farmer expressed an opposing sentiment when it comes to gay marriage: "Everybody to their own...It's not something they choose, it's something that is bestowed upon them. It's the way it is. It's like having a family full of girls, you can have a family gay or straight."

Some students at Sligo IT were also asked about their views and while the majority of under-35s are considered to be in favour of a Yes vote. One student relayed his concern about gay mrriage and parenting: "If you had two fathers and you're going to school you'd be seen as the outcast."

The number of certain Yes voters is on 44%, but that much of the support could be soft - and could potentially be lost in the run-up to polling day.

Some 59% agree strongly that they will vote Yes to change the Constitution, with 18% only agreeing tentatively.
